Step-by-step explanation:
Opposite angles are congruent. So the correct answer is A. x=118
Hey there! :)
Answer:
118 children
58 students
59 adults
Step-by-step explanation:
We can solve this problem by setting up a system of equations:
Let a = adults
2a = children (since double the # of adults were children), and
s = students
Set up the equations:
1704 = 5(2a) + 7s + 12(a)
1704 = 10a + 7s + 12a
235 = 2a + a + s
Simplify the equations:
1704 = 22a + 7s
235 = 3a + s
Subtract the bottom equation from the top by multiplying the bottom equation by 7 to eliminate the 's' variable:
1704 = 22a + 7s
7(235 = 3a + s)
1704 = 22a + 7s
1645 = 21a + 7s
---------------------- (Subtract)
59 = a
This is the number of adults. Substitute this number into an equation to solve for the number of students:
235 = 3(59) + s
235 = 177 + s
s = 58.
Since the number of children is equivalent to 2a, solve:
2(59) = 118 children.
Therefore, the values for each group are:
118 children
59 adults
58 students.
When doing vertical subtraction, 800 - 675 will turn out like this:

</u>You should know that we start on the right and then end on the left.
<u>
</u>So, we do 0 - 5, 0 - 7, then 8 - 6, right?
No. We have to borrow because you can't have a negative number when doing each number individually, only until the end. In this case, there won't be any negative numbers.
<u>
</u>You can't do 0 - 5 or 0 - 7, so you have to borrow, changing the number to the left of it one lower (unless it's 0, so then you must borrow the the next number after that).<u>

Answer:
number 2
Step-by-step explanation:
from the original equation you can multiple the m to the x's first.
y-y1=mx-mx1
if you moved mx1 to left the sign will change from - to +
so you y- y1+mx1= mx
then to get x
(y- you + mx1 )/ m = x
